REENFORGED GLASS.

Application filed February 28, 1927. Serial No. 171,545.

rlhis inventionA relates to improvements inreentorced glass, and tothe method of placing the reenter-cement in the glass.

l'li`he Adevice providesa means whereby the reentorcing material is so arranged that adequate reen'lforcement ot any desired area is obtainable, while at the same time an unreeniforced clear vision area is provided which may be at a point intermediate two reen'l'orced areas, or at one side only of such reeniforced area.

An object is to so dispose the reeniorcing material, that smaller sections oi reenlorced transparent material oi any size can be con- -veni-ently cut itrom a section of larger size, so that the cut out section provides, if desircd, a pane of glass having two strips of reeniorcing material, extending inwardly i'rom opposite edges, with the strips spaced and substantially parallel, to provide an un.- recni'orced clear vision area therebetween. The clear vision and reeni'orced areas are strip-lilre and are parallel. Thus, when the glass is set in its trame, some reenforcing material may be had at the top and at the bottom of the window, or at the top only, or at the bottom only.

rlhis device and method are particularly adapted itor use on public carriers, such as automobiles, street cars, etc., and is also well adapted `tor use in the manufacture ot wind shields, in all ot which uses sufficient reenforcement is provided. to prevent flying of the glass in case of breakage, while at the saine time clear and ni'iobstructed vision can `be had, arranged at any convenient level.

Features oit the invention include the method of arranging the reen'forcement to obtain the above mentioned results, as well as the article produced by the method.

Advantages oi the device will be set :forth in the description olf the drawings forming the strips parallel and spaced apart to form the clear vision area 3. As herein shown, the distance A between the parallel reenforcing strips is greater than the `width `B ot the strips. It will be understood, however, that the widths of the reent'orcing strips may vary as well as the widths ot the clear vision space between the strips, and it will be further understood that in.` a given `section oit' glass 1, the widths ot all reentorcing sections may not necessarily be the same. This will also be true ot the widths of clear vision areas. By this arrangement, it will bc seen that smaller sections represented respectively by dotanddash lines C, D, E of varying dimensions, in direction F, as well as in a direction lengthwise of the strips, can be cut so that varying amounts of marginal reenforcement may, in some instances, be provided at opposite sides, which sides when the glass is in the window are arranged at the top and bottom of the window, to provide an unreenliorced clear vision space or area 2 intermediate the reeni'orced top and bottom areas. It will be understood that it is not necessary that reenforcing materials or strips be of equal width at the top and bottom, and it will be `further understood that two areas, respectively reeniforced and clear vision, only may be provided as indicated at E in Figure 1. The relative widths ot these areas may also be varied. It may be advanta geous to have more reenlforcing material atV the top than at the bottom or vice versa. It will, however, be seen that smaller pieces of glass may be conveniently cut Afrom the larger section 1 in almost any combination ol reentorced and clear vision areas.

I claim as my invention: y

1. A section ot transparent material having strips of reenforcing material embedded therein, the strips being spaced to provide an unreenforced clear vision area.

2. A section of transparent material having parallel strip-like reen'forcedand unreenforced portions formingV alternating striplike areas.

3. A section of transparent material having parallel strips oi open wire reeniiorcing material -embedded therein, the strips being spaced to provide an unreeiniorced clear vision area.`

4. A section of transparent material havmg strip-like reenforced and unreenforced portions forming alternating strip-like areas,

the reenforoeel areas being greater Ithan the unreenlo-reeel areas.

5. A section of transparent material having parallel strips of open Wire reenlorcing material embedded therein, the strips Abeing spaced to provide an unreenforeed clear vision area, the area of the re-en'lioreed por tion being greater than the area between the reen-forced portions.

:6. Section of glass having' ,alternate reenoreed and mare-enforced areas arranged tolpermiit'the severance 'therefrom of smaller sections oli varying size, so that each :seetion refresher may have an ntermediately .disposed unreenloreed area flanked by reentliorred `areas.

7. A section of transparent material hai# ing alternate reenioreed and unreenforeed area-s arranged to permit severance therefrom into smaller sections of varying size, to provide sections havin` either an intermedatelydisposedtimreenforced area lanked by reenforced areas or having only reenloreed und unreenliorced arena ln .witness whereof, l ha e hereuarte eet, my hand vthi@ 525th day rel' February will.
